Excellent cluster of superb Pyrite crystals from the famous Madan ore field, Bulgaria. The brassy Pyrites are sharp cubic crystals growing in a very unusual structure. They are strongly lustrous and light reflective with pleasing yellow color. The faces have nice striations. Small Sphalerite crystals grow above. Complete all over 360 degree. In very good condition – some small damages. On acrylic base.

Wonderful!
